Rust Color

==========

### Compile time color parsing

```rust

use color::{rgba, RGBA};

#[test]

fn test_rgba() {

    assert_eq!(rgba!("#334D6677"), RGBA::new(51, 76, 102));

    assert_eq!(rgba!("rgba(51, 77, 102, .5)"), RGBA::new(51, 77, 102, 127));

    assert_eq!(rgba!("rgba(20% 30% 40% 50%)"), RGBA::new(51, 77, 102, 127));

}

```

![success](https://user-images.githubusercontent.com/17541209/156918397-cf9024dc-7f2e-4f36-b3a7-2eec1cb26584.png)

### Compile time error report

```rust

// Invalid hex pattern, can take 3,4,6,8 hex number only

rgba!("#34678");

```

![failure](https://user-images.githubusercontent.com/17541209/156918188-e8d6ed8c-b811-4f20-9159-040eeab5af07.png)

### Strict check mode

```toml

features = ["strict"]

```

Normally valid mode is looser than specified, strict mode rejects all non-css level3 input

```rust

// will not panic by default

rgba!("rgba(10 10 10, 10)");

```
